Materials should normally be stored under cover. Reduced shelf life may occur if packaging is exposed to the elements. Packaging materials may deteriorate, allowing moisture ingress into the cementitious binder. This could lead to premature hardening.
Roof Bolt Grout products will store for up to 6 months in dry conditions.
|General||The use of eye protection, gloves and dust masks is recommended. Follow the typical precautions as prescribed for handling Portland cement.|
|Inhalation||Constant exposure over long periods of time to very high concentrations may cause a cough with phlegm.|
